All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an aspect of the embodiment of the present invention, there is provided a data transmission method, optionally, as an optional implementation manner, the above data transmission method may be applied, but not limited to, in the environment shown in fig. 1.
In fig. 1, the client may be implemented in a user equipment 102, where the user equipment 102 includes a memory 104 for storing data to be forwarded, and a processor 106 for processing the data to be forwarded. The user equipment 102 sends the data to be forwarded to the server 112 via the target communication channel 110, which is determined by S102-S106. The server 112 includes a database 114 for storing data to be forwarded and a processing engine 116 for processing the data to be forwarded. As shown in fig. 1, data to be forwarded acquired on the client may be sent to the server 112.
Optionally, the data sending method may be, but not limited to, applied to a client running on the user equipment 102 that may forward data, where the user equipment 102 may be a mobile phone, a tablet computer, a notebook computer, a PC, etc., and the target communication 110 may include, but is not limited to, a plurality of network nodes, where the network nodes are connected by a network dedicated line. The server 112 may include, but is not limited to, any hardware device that can perform calculations.
Optionally, as an optional embodiment, as shown in fig. 2, the data sending method includes:
s202: acquiring a data forwarding request, wherein the data forwarding request is used for requesting to send target data from source network equipment to target network equipment;
s204: responding to the data forwarding request, and determining a target network node configured with special line communication resources in a communication network;
s206: generating a target communication channel for transmitting target data according to the target network node;
s208: the target data is sent from the source network device to the target network device in the target communication channel.
Optionally, in this embodiment, the above data sending method may be, but is not limited to, applied to a scenario where data needs to be sent, for example, in a cross-domain service scenario of a game, the problem of large delay of a cross-domain public network and high packet loss rate may be faced in the network aspect, which results in poor experience of a player of an instant combat game, and network acceleration is performed by using a network dedicated line, so that low-delay and low-packet loss network transmission of a game service can be realized. Wherein the source network device may be, but is not limited to being, a plurality of clients in an area, and the target network device includes, but is not limited to being, a source station server in an area.
Alternatively, for example, in the case where the source network device is a plurality of clients and the target network device is a source station server, a target communication channel between the source network device and the target network device is as shown in fig. 3, and interaction of data is performed between the clients and the source station server through the target communication channel. The source station server is deployed in the area B, the client side of the area A accesses the source station server of the area B, only the access point accesses the virtual IP VIP+port number PORT to enter a target communication channel, and target data is transmitted to a destination through the target communication channel and then forwarded to the configured source station server.
Alternatively, for example, the target communication channel may be configured by:
s1, creating a target communication channel according to an acceleration area accessed by a client and a source station area where a source station server is located, wherein the target communication channel comprises a name defining the target communication channel, the source station area where the server is located and the acceleration area accessed by the client as shown in figure 4.
S2, after the target communication channel is established, setting an access virtual IP VIP and an access range Domain of the target communication channel. For example, as shown in fig. 5, a channel name defining a target communication channel is "Link-93rwj9zl qaaptest", VIP is "49.51.66.61", and a domain name is "Link-93rwj9zl.
S3: the source station server information is entered and the internet protocol IP address or domain name of the destination communication channel may be selected as shown in fig. 6.
S4, creating a listener of the target communication channel and binding a corresponding source station server. The monitor is used for determining an access Port of the client, and the access Port supports the custom specification of the client and can also generate the access Port. The player accesses the target communication channel by accessing vip+port, and the access request is forwarded to the bound source station server. For example, as shown in fig. 7, the Listener may be "Listener-4rk54tg7111", the forwarding protocol used is "transmission control protocol (Transmission Control Protocol, abbreviated as TCP)", the source port is "111", the bound source server is "11.11.11.11", the source type is "IP address", and the service status is "normal".
Through the embodiment, through simplified configuration of the target communication channel, the client can realize special line acceleration only by specifying the access area, the source station area and the source station server information, and the efficiency of data transmission is increased.
Optionally, the target communication channel includes a plurality of target network nodes, and the target communication channel may include a plurality of target network nodes. And determining an optimal target communication channel from the multi-item label communication channels by using a four-layer data transmission algorithm. The link formed by the target network nodes in the target communication channel is the shortest link, and the delay period for forwarding the target data is high in efficiency.
Optionally, in this embodiment, the target network nodes may be connected by a dedicated line, and dedicated line acceleration of the target data may be implemented by Anycast. The forwarding mode of Anycast enables the public network request of the user to select the nearby network node to enter, and improves the quality of the transmission link. Essentially, anycast is adopted in the addressing link based on a public network IP. The principle is as follows: common IP is unicast addressing, which goes through the public network. If Anycast is used, the public network IP addresses in an Anycast mode, routes are sent at a plurality of network nodes, data to be transferred of the client only need to travel the public network to reach the nearest network node, and the rest path can travel a more guaranteed intranet. Namely, the long-distance public network transmission is changed into the self-built intranet transmission, so that the acceleration effect is realized.
Alternatively, in the present embodiment, the four layer data transmission algorithm includes, but is not limited to, full network translation Fullnat, which is essentially a combination of source address translation snat+destination address translation Dnat. The four-tuple data of the network device corresponding to one target network node includes < source IP address: source port: destination IP address: destination port >. When forwarding is performed in the Fullnat mode, the source IP address and the destination IP address are replaced. I.e. the source IP address is converted into its own IP address, the destination IP address is converted into the next hop IP address, e.g. the destination data is forwarded from network node a to network node C, the intermediate network node B is needed, the source IP address of the destination data is converted into the IP address of a, and the destination IP address of the destination data is converted into the IP address of B. After the data to be forwarded is sent to the point B, the source IP address of the target data is converted into the IP address of the point B, and the destination IP address of the target data is converted into the IP address of the point C.
According to the embodiment, the target communication channel is determined through the four-layer data transmission algorithm, so that the IP address of the next hop of the target data is determined, and the optimal path for forwarding the target data can be determined, thereby improving the data transmission efficiency, reducing the time delay and improving the game experience of a game player.
In an alternative embodiment, determining a target network node configured with dedicated line communication resources in a communication network comprises:
s1, determining a network equipment cluster built in each region in a communication network, wherein each network equipment in the network equipment cluster is used as a network node in the communication network;
s2, taking the network node corresponding to the network equipment which is determined from the network equipment cluster and is configured with the special line communication resource as a target network node.
Alternatively, in this embodiment, as shown in fig. 8, a network device cluster is set up in each region, and each network device in the network device cluster will be a network node in the communication network. Network nodes include, but are not limited to, various types of cloud nodes or custom nodes, etc., which may cover various territories. Pulling network leased lines between network nodes, such as: the network nodes are opened up by a cloud network or peer-to-peer connection. And communicating with other cooperative cloud networks through a private line. The network private lines connecting the network nodes form the edges of the forwarding network. Because of the transitivity of the fulnnat mode, as shown in fig. 8, the communication between the region a and the region B, and the communication between the region B and the region C can be realized, so that the network transmission between the region a and the region C can be realized.
According to the embodiment, the network nodes with the connection establishment capability are connected through the network private lines, all the network nodes can be communicated only by a few network private lines, even a cloud manufacturer only needs one network private line, the intercommunication cost among cloud manufacturers is greatly reduced, and the coverage range of a cloud network is enlarged.
In an alternative embodiment, generating a target communication channel for transmitting target data from a target network node comprises:
s1, acquiring four-tuple data of network equipment corresponding to a target network node, wherein the four-tuple data comprise: a source IP address, a source port, a destination IP address, and a destination port;
s2, determining a target communication channel according to the four-tuple data.
Optionally, in this embodiment, one quadruple of data includes < source IP address: source port: destination IP address: destination port >. When forwarding in the fulnnat mode, the source IP and the destination IP are replaced, as shown in fig. 9, i.e. the source IP is converted into the own IP, the destination IP is converted into the next-hop IP, for example, the destination data is forwarded from the network node a to the network node C, and if the destination data needs to pass through the network node B in the middle, the source IP address of the destination data is converted into the IP address of a, and the destination IP address of the destination data is converted into the IP address of B. After the data to be forwarded is sent to the point B, the source IP address of the target data is converted into the IP address of the point B, and the destination IP address of the target data is converted into the IP address of the point C.
Optionally, the four-tuple data may also be Req < Access, dest, RSIP, RSPort >, respectively representing acceleration region, source region, IP/Domain of the server, server port. In this embodiment, as shown in fig. 10, after determining that the four-tuple data Req: < Access, dest, RSIP, RSPort >, the four-tuple data is sent to the route Manager, where the route Manager generates a Region List corresponding to the four-tuple data, where the Region List includes a forwarding link for forwarding the target data. The target communication channel may be determined from the forwarding link. The Region List sends the forwarding link to Proxy Manager, and the Proxy Manager encapsulates the forwarding link and the media gateway control protocol command RSIP RSPort corresponding to the quadruple data into a forward rule, namely a fulnnat forwarding rule, where the fulnnat forwarding rule includes a target network node in the target communication channel, and also includes an IP address and a forwarding port from each network node to a next hop network node. And sending the Fullnat forwarding rule to a rule control server, and distributing the Fullnat forwarding rule to each network node Agent by the rule control server. The Agent learns the target communication channel and the network node forwarded by the next hop from the Fullnat forwarding rule so as to send the target data to the source server.
According to the embodiment, the target communication channel is determined through the four-layer data transmission algorithm, so that the IP address of the next hop of the target data is determined, and the optimal path for forwarding the target data can be determined, thereby improving the data transmission efficiency, reducing the time delay and improving the game experience of a game player.

Optionally, in this embodiment, the access domain name and the access port may be determined by route management in the forwarding network, as shown in fig. 10, where the route management is responsible for managing the forwarding network, including cluster machine management, fault machine rejection, cluster scaling, dedicated line quality and packet loss rate detection, dedicated line topology network maintenance, and so on. After a user designates an acceleration area accessed by a client and an area where a source station server is located, route management is performed according to the acceleration area: and the source station area is used for distributing a link message by combining the current special line quality.
In this embodiment, the weight of the edge in the forwarding network is a comprehensive consideration of the comprehensive delay and packet loss, and the shortest path algorithm is used to select the best link.
According to the embodiment, the forwarding path of the target data can be determined, the optimal link is selected, and the efficiency of data transmission is improved.
In an alternative embodiment, transmitting the target data from the source network device to the target network device in the target communication channel includes:
s1, under the condition that a target network node comprises a plurality of forwarding devices, setting the weight of each forwarding device in the plurality of forwarding devices by using a dynamic port mapping;
s2, determining a target forwarding device for forwarding target data at a target network node according to the weight of each forwarding device;
and S3, transmitting the target data from the source network device to the target network device by using the target forwarding device in the target communication channel.
Alternatively, in the present embodiment, as shown in fig. 11, it is assumed that transmission is performed between cluster a and next hop cluster B through the intranet. Forwarding rules corresponding to machine A1 may be generated:
thereby determining the forwarding weight of each cluster and realizing the function of load balancing.

And sending forwarding instructions to each network node after all network nodes are configured for updating.
According to the embodiment, a forwarding algorithm is required to be issued by a forwarding link on a plurality of machines in a plurality of clusters, so that the consistency and the correctness of a forwarding task are guaranteed in order not to influence the forwarding of the current forwarding rule, and a forwarding configuration instruction is issued only after all configuration files are updated and check configuration files, so that the consistency of forwarding rule change is guaranteed.
In an alternative embodiment, transmitting the target data from the source network device to the target network device in the target communication channel includes:
s1, determining link information of forwarding target data, wherein the link information comprises at least one of the following: the method comprises the steps of accessing area information of source network equipment, area information of target network equipment, an initial network node of target data, a target network node of the target data, network information of a network node through which the target data is forwarded, information of forwarding equipment for forwarding the target data and cluster information of the target network node;

and S3, under the condition that the second fault information is received, determining that the target network equipment fails.
Optionally, in this embodiment, the first failure information is used to identify whether the target network node is failed, i.e. that mutual checks between the target network nodes can be performed. For example, the network node agent detects the IP of the next-hop network node by using a tcppling mode, if the detection result is not good, the next-hop network node fails, and the agent can reject the forwarding rule of the next-hop network node in the forwarding configuration.
Optionally, in this embodiment, the second fault information is used to identify whether the target network device has a fault. For example, in the case where the target network device is a source station server, the last network node in the target communication channel has a function of detecting whether the source station server has failed. And under the condition that the second fault information sent by the last network node is received, determining that the source station server fails.
According to the embodiment, the second-level rejection function of the fault node can be realized through second-level triggering detection and inspection. The second-level switching and alarming functions can be realized, the reliability and stability of the forwarding rule are further improved, and the forwarding quality is ensured.
In an optional embodiment, the forwarding network in this embodiment further includes a Control Server module, which is mainly used for management of the agent and issuing of the forwarding algorithm. After the rule module generates the forwarding algorithm, the forwarding algorithm is uniformly submitted to the Control Server module for issuing. The Conrtrol Server module is responsible for establishing connection with the agents on the forwarder, maintaining the long connection with the agents through the Hear Beat and recording connection information. When receiving the forwarding rule of the rule module, the module can find the corresponding connection through virtual_server information and send the corresponding forwarding responsibility to the agent of the corresponding machine.
In summary, the embodiment is based on the forwarding mode of Fullnat, so that the network forwarding is transitive. The construction of the forwarding network becomes simple, and the acceleration Mesh network covering the whole world can be constructed by using fewer special lines. Based on detection of special line packet loss and time delay and a shortest path algorithm, the routing module can select a link with the best quality in the current accelerating network to realize construction of a forwarding four-layer link. Meanwhile, the routing module can dynamically monitor the change of the routing, and can immediately trigger the link switching when the special line fails. Based on Fullnat forwarding algorithm, the configuration is simple, the current node only needs to pay attention to the forwarding of the next hop, the configuration is simple, the configuration generation of the forwarding algorithm can be realized in a second level through the forwarding algorithm of Control-Agent. Even if a private line fails, the delivery from the detection of a new forwarding configuration is on the order of seconds. The implementation of the health checking mechanism can realize the second-level rejection of the fault transponder and ensure the stability of the forwarding link. The dynamic port mapping scheme of the rule management module enables the machines to be multiplexed, and the same forwarding cluster can meet a plurality of different forwarding requirements.
